HEATER.

Application filed. April a, 1918.

To all whom it may concern:

Be it known that I, PA'rnicn Ronennn, a citizen of the United States, residing at Fond du Lac, in the county of Fond du Lac and State of Wisconsin, have invented a new and Improved Heater, of which the following is a full, clear, and eXact description.

My invention relates to a heater of the sectional type, the heating of which depends on hot gas circulating therethrough. The heater generally forms a by-pass or branchout of a flue or heat-conveying conduit, so as to provide a large heat-radiating area for the hot gas circulating through the flue or conduit.

An object of the invention is to provide a simple, inexpensive and efficient heater of the character described which can be easily connected to a chimney or stovepipe to utilize the heat carried by the gases within the stovepipe or chimney before the gases escape into the atmosphere.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combina tion and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in both views.

Figure 1 is a section through a heater embodying my invention, shown connected to a conductor of hot gases; and

Fig. 2, an elevation of a heater embodying my invention shown connected to a flue or Smokestack or chimney, the latter bleing shown in section.

Referring to the drawings, 3 are the sections forming the heater. As shown, there are three sections. It is self-evident that the number of sections may be varied to vary the height of the heater. The diame ter of the sections may also be varied to vary th surface of radiation. Each of the sections is provided with a batlie or deflector i, in the shape of an inverted cone the base of which is of a diameter less than that of the section, so as to provide an annular passage 5 in proximity to the inner periphery of the section. The circular area or clearance of the annular passage 5 1s substantially equal to the cross-sect1onal area of the Specification of Letters Patent.

sectional conduit 6 which leads the hot gas from the main conduit 7.

It will be noted that each section 8 of the conduit 6 is connected to a corresponding section 3 of the heater, and the two, that is, the sections 3 and 6, are so related that the placing of one heater section upon another heater section brings also'into engagement the conduit sections 8. Preferably the means 9 which connect the conduit sections 8 to a heater section 3 is of a type to allow the tubular section 8 to swing on the connection to compensate for any unevenness in manufacture and allow the alinement between the conduit sections 8 in building up the heater.

The lowermost section 3 is connected by an elbow 10 to the conduit section 8 so as to provide an easy inflow of hot gases into that section. The lowermost section 3 is closed by a box 11, .fOlHliIlg the bottom of the heater, which fits sinigly and endwise into the section and is retained thereat by thumb clamps 12. In this box soot and other material will accumulate naturally or when cleaning the heater.

The uppermost section 3 of the heater is provided with a cover 13 which has a conduit 14 of a diameter substantially equal to the conduit 8 and which is fitted into the mai conduit 7. The conduits S and 14- are separated by a gate 15 within. the main conduit 7 so that the hot said gate into the conduit 8 to the heater, out through the conduit 14 and back into the main conduit 7 The hot gases coming into the heater are deflected by the baflies 4 against the inner periphery of the sections 3, whereby the efficiency of the heater is increased, for the hot gases are maintained in close proximity to the radiating surface.

In Fig. 2 the heater is connected to a chimney and the inlet conduit 8 for the hot ga es is separated from the outlet conduit 14 by a gate 15. It will be noted that it is not material whether the main conduit 7 is horizontal or whether the chimney 16 is vertical. The inlet conduit 8 precedes the outlet conduit 14- in the direction of the flow of the gases.

The lowermost section is preferably provided with legs 17 to maintain the box 11 clear of the floor to facilitate the removal of same.

gases are deflected by I claim:

1. A heater of the character described, comprising a casing provided at its top with a cover from which leads a conduit and at its bottomwith a removable closure, a plurality of inverted cone-shaped battles in the casing and each forming with the casing an annular passage, and a longitudinally extending conduit at one side of the casing and having its lower end opening into the said casing a short distance above its bottom, the conduit being of a length approximately equal to that of the casing.

, 2. A sectional heater comprising a cylindrical sectional body, an inverted coneshaped baflie within each section, means supporting the bafiles so that an annular passage is formed by the baffles with the cylindrical body, a sectional tube having its lower end communicating with the lower portion of the heater, and means pivotally connecting the sections of the tube with the sections of the body.

3. In a heater of the character described,

a cylindrical body formed of sections, a

tube formed of sections and extending longitudinally of the body, the tube having its lower end comniumicating with the body, and means for pivotally connecting the sections of the tube with the sections of the body.

4. A heater of the character described, comprising a casing formed of a plurality of sections, a baffle in each section, and a longitudinally extending conduit formed of a plurality of sections secured to the sections of the casing, the conduit having its lower end opening into the lower end of the casing.
